IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 219,043, dated August26, 1879; application filed April 9, 1879.

To all whom it may concern:

Be it known that I, SAMUEL LLOYD WA- TEES, of Genoa, in the county of DeKalb and State of Illinois, have invented anew and useful Improvement inHarrows, of which the for connecting the beams with' the draw-rod tubes.Fig. 4 is a detail of one of the washers for connecting the knives withthe beams.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved harrow forloosening, pulverizing, and smoothing land, which shall be simple inconstruction, convenient in use, and effective in its operation, leavingthe ground in fine condition to receive the seed.

The invention consists in the harrow-frame formed of the rod bent in itsmiddle to form a loop or bail, and having its arms parallel andconnect'd by cross-rods, the tubes, the beams,

, the U or staple bolts, and the brace-rods; in the construction of theharrow-knife; in the blocks or washers interposed between the tubes andthe beams, concaved upon their opposite sides I to receive the saidtubesand beams, and perforatedto receive the arms of the U or staplebolts, and provided with a pin to enter a hole in the tubes B. I

A is the draw-rod, which is bent together at it's middle to form a bailhaving an eye at its center for convenience in attaching the draft.

The end parts or arms of the rod A are straight and parallel with eachother, and are connected at their-forward and rear ends and middle partsby cross-bars a Upon each of the arms of therod A are placed as manyshort tubes Has there are to be beams 0 upon The tubes B are made of alength equal to the required distance apart of the said beams O, and aresecured in place upon the said rod A by nuts a screwed upon its ends. 1g y The beams U are also made of tubes, and

each one, at a little .distancefrom its inner end, is secured to one ofthe tubes B at a little bolts D, which pass around the tube B, throughthe tubes 0, and have nuts screwedupon their ends.

E are washers or collars, which are interposed between the beams O andthe tubes B. The washers E are concaved longitudinally upon their lowersides to rest and fit upon the beams O, are concaved transversely upontheir upper sides to receive and fit upon the tubes B, and are providedwith a pin to enter a hole in the said tubes B.

The transverse grooves of the washers E are inclined at the angle atwhich it is desired to have the outer ends of the beams U incline to therearward. The beams 0 are further strengthened in position by thebrace-rods F, the outer ends of which are attached to the "said beams,and their inner ends are attached to the rear ends of the tubes B. Thisconstruction allows the beams O to adjust themselves to an unevensurface of ground, each beam moving independently of the others.

G are the knives, the shanks of which are secured to the forward side ofthe beams G by the staple-bolts H, both arms of which pass through theforward side of the said beams, and one arm passes through bothsides ofthe .one side to better adapt them to loosen up and pulverize the soil;The knives G are twisted in opposite directions upon the alternate beamsO, as shown in Fig. 1. The knives of the rear beams are made more nearlyvertical and without so much twist, and are designed to smooth off theground after being loosened and pulverized by the knives of the forwardbeams.

Having thus described my invention,Ielaim. as new and desire to secureby Letters Patent- 1. The harrowframe formed of the rod A,

distance from its forward end by U or staple bent in its middle toform'a loop or bail, and

having its arms parallel and connected by cross-rods a, the tubes B, thebeams O, the U or staple bolts D, and the brace-rods F, substantially asherein shown and described.

2. A harrow having bars set transversely to the line of draft andprovided with curved twisted knives G, alternately inclined'towardopposite sides on adjacentbars O, as shown and described.

3. The blocks or washers E, interposed bestantially as herein shown anddescribed.
